Gemini 4 Carbon: Google's strongest model goes first to cyber defenders
Google announced Gemini 4 Carbon on Wednesday, calling it its strongest model, with state-of-the-art cybersecurity and long-horizon skills. Access starts this week with a subset of cyber defenders and widens to trusted partners through the Fairwind Program; Google's post gives no date for developers, businesses and consumers. By Google's own figures it scores 88.2% on SEC-bench Pro, and the introductory API price is $2 and $10 per million input and output tokens.
What it means for youif you build on Gemini, wait for Google to open Carbon to developers.
AidenGemini 4 Carbon is Google's strongest model yet, Google says, and a subset of cyber defenders get it first.
AidenJonah, our AI products analyst. Who gets it, and when?
JonahCyber defenders start this week. Google says access then widens to trusted partners through its Fairwind Program. Developers, businesses and consumers come after that, and the post gives no date. The introductory API price is $2 per 1M input tokens and $10 per 1M output.
AidenOne question we checked: does its cyber lead come from special fine-tuning, or from general reasoning?
JonahGoogle's post doesn't say how the cyber skills were trained. It reports gains in coding and agentic tasks too, and 88.2% on SEC-bench Pro for finding vulnerabilities. Those are Google's own figures.
AidenSo, for you: if you build on Gemini, wait for Google to open Carbon to developers.

Mistral Large 4: open weights for the 1-trillion-parameter model
Mistral released the weights of Mistral Large 4 today, a roughly 1-trillion-parameter mixture-of-experts model with reasoning and image input, on Hugging Face. The licence is a modified MIT; companies offering it as a hosted model service need a separate commercial licence. Mistral says it scores 41% on Terminal-Bench 4.0, its own figure.
What it means for youwithout a GPU cluster, try it through Mistral's API or OpenRouter first.
AidenMistral Large 4's open weights are on Hugging Face today: a 1-trillion-parameter model you can use commercially, with one licence catch.
AidenJonah, our AI products analyst. What's the catch, and what does it take to run?
JonahThe licence is a modified MIT. You can use, modify, fine-tune and sell with it. The catch: a business offering it as a hosted model service needs a separate commercial licence from Mistral.
AidenAnd the hardware? 1 trillion parameters sounds big.
JonahIt is. Hugging Face's guide hosts it on 8 H200 GPUs. Its 2-bit versions run on one Apple Silicon Ultra with 512 GB of unified memory. Mistral's API is $0.70 per 1M input tokens. And Mistral says it scores 41% on Terminal-Bench 4.0, its own figure.
AidenSo, for you: without a GPU cluster, try it through Mistral's API or OpenRouter first.

Marvell is in talks to buy AI optics maker Lumentum, Bloomberg reports
Bloomberg, citing unnamed people, reported on Wednesday that Marvell Technology is in talks to buy Lumentum, and that a deal could be announced as soon as next week. No final deal has been reached and details could change. After Wednesday's close Lumentum was valued at about $83 billion and Marvell at about $221 billion.

AidenMarvell is in talks to buy Lumentum, a maker of optics for AI data centers, Bloomberg reported yesterday, citing unnamed people.
AidenNora, our AI hardware analyst. How big is this, and why optics?
NoraBig. After Wednesday's close, Lumentum was worth about $83 billion. Its CEO has said it is effectively sold out of some products into 2029.
AidenOne question we checked: why buy the supplier instead of signing a long-term supply deal?
NoraThe report we checked doesn't give Marvell's reasons. The article's own reading is that a deal could give Marvell scarce optical parts.
AidenAnother question we checked: does China need to approve the deal?
NoraThe report we checked doesn't say. It says there's no final deal yet, and details could change. A deal could be announced as soon as next week.

ChatGPT dots: US Pro users can text their dot over iMessage or RCS
OpenAI's release notes of Wednesday, October 28 say texting your dot is starting to roll out in beta to Pro users in the US, over iMessage or RCS. The dot shares the same memory and plugins as in the ChatGPT app and can text you with updates; only you can text it, and OpenAI says it gets no access to your other text conversations.
What it means for youthe beta started rolling out yesterday, so Texting may not show up for you yet.
AidenOn ChatGPT Pro in the US? OpenAI's new beta lets you text your dot over iMessage or RCS.
AidenJonah, our AI products analyst. How does it work?
JonahA dot is OpenAI's always-on agent in ChatGPT. To start, open your dot's profile in ChatGPT and select Texting. You need iMessage on an iPhone or RCS on Android. It shares the same memory and plugins as your dot in the app. And the dot can text you first, with updates that may be relevant.
AidenOne question we checked: can the dot work in a group chat, or for more than one person?
JonahThe release notes don't mention group chats. They say your dot can only text you, and you're the only one who can text it. OpenAI says it gets no access to your other text conversations.
AidenAnother question we checked: is there a setting so it only texts about important things?
JonahThe release notes don't say. They do say the texts go through Linq, a third-party messaging provider.
AidenSo, for you: the beta started rolling out yesterday, so Texting may not show up for you yet.
